do send a datalog but you have replaced a lot of parts.

that is really damn frustrating

have reviewed your list of stuff you've done and determined that it's likely that one of your replacements or measurements is incorrect or you've missed something fundamental

a compression test is great but what if you have an intake or exhaust leak it wouldn't capture that

it's like 'hey i have drawn a straight line which my ruler says is straight but everything else says its bent' well maybe your ruler is bent.

the fact it goes to hell in closed loop but you have replaced the sensors indicates a possible o2 wiring/grounding issue or massive metering issue like a really big exhaust leak pre o2 sensor
